    • The nucleic acid sequence of the full-length, chemically inducible Arabidopsis PR-1 promoter has been discovered and is disclosed herein. Furthermore, cis-acting regulatory elements in the Arabidopsis PR-1 promoter involved in chemical induction have been characterized using deletion and linker-scanning mutagenesis and in vivo footprinting. It has been discovered that at least a portion of the region of promoter between positions -698 and -621 (relative to the transcription start site of the PR-1 gene) is required for induction of gene expression by chemicals. Two 10-bp linker-scanning mutations centered at 640-bp and 610-bp upstream from the transcription start site abolish the inducibility of the promoter while another 10-bp mutation centered at -670 bp results in average induced expression levels 4-fold higher than the unmutated promoter. Additionally, inducible in vivo footprints are located at positions -629 and -628 and at position -604 on the coding strand and at position -641 on the non-coding strand. The use of chemically inducible Arabidopsis PR-1 promoter fragments to regulate gene expression in plants in the presence of inducing chemicals such as SA, INA, and BTH is disclosed, as well as the use of these elements for the isolation of transcriptional regulatory proteins involved in the promoter regulation and for the construction of inducible hybrid promoters.
    • 已经发现了全长化学诱导型拟南芥PR-1启动子的核酸序列,并在此公开。 此外,参与化学诱导的拟南芥PR-1启动子中的顺式作用调节元件已经使用缺失和连接物扫描诱变和体内足迹进行表征。 已经发现,通过化学物质诱导基因表达需要至少部分-698和-621位点之间的启动子区域(相对于PR-1基因的转录起始位点)。 以转录起始位点上游640-bp和610-bp为中心的两个10-bp接头扫描突变消除了启动子的诱导性,而另一个以-670bp为中心的10-bp突变导致平均诱导的表达水平高4倍 比未突变的启动子。 此外,可诱导的体内足迹位于编码链上的位置-629和-628,位置-604位于非编码链上-641位。 公开了使用化学诱导型拟南芥PR-1启动子片段在诱导化学物质如SA,INA和BTH存在下调节植物中的基因表达,以及这些元件用于分离涉及转录调节蛋白的用途 在启动子调节和诱导型杂合启动子的构建中。
